... IC. Forward Over-Current Protection The APA2070 monitors the output current. When the cur- rent exceeds the current-limit threshold, the APA2070 turns off the output to prevent the IC from damages in over- current or short-circuit condition. When the over-current occurs in power amplifier, the output buffer’ ...
